I know back in the days when PC100 was new and the prices came down a little bit, but still really expensive, a few manufactures pirated a lot of PC66 and made some changes to have it work like PC100. but it wasn't stable. maybe people are doing that with pc133.. it wouldnt surprise me. --- doug reynolds | the maverick | mav@wastegate.net PGP Public Key Fingerprint: 6E7B 9993 B503 6D45 E33A 2019 26E5 C1DB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
